AUTOMOBILE-HORN.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed January 16, 1914. Serial No. 812,410.

To all whom it may concern:

Be it known that I, WVILLAR PENNOOK, a citizen of the United States, residing at Minerva, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Automobile-Horns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to signals and more specifically to horns such as are used on automobiles and the like.

The objects of the present invention, are first, to provide a horn wherein pipes or tubes are employed which sound a chime or chord, and second, to utilize the air and gases escaping from the exhaust of the motor or engine such as common in automobiles. These objects, together with other objects readily apparent to those skilled in the art, I attain by the construction illustrated in the accompanying drawing, although my invention may be embodied in a variety of other mechanical forms, the construction illustrated being chosen by way of example.

In the drawingsFigure 1 is a perspective view showing the parts in position for use as a horn. Fig. 2 is a side elevation showing the exhaust pipe broken and one end of one of the tubes partially in section. Fig. 3 is an end view showing the cover or cap partially broken away. Fig. 4 is a longitudinal section of the exhaust pipe, one of the tubes showing the exhaust pipe open or in normal condition. Fig. 5 is a similar view showing the cap or cover closed and in the position to cause sound to be produced.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, 1 represents the head or sleeve, to which the exhaust pipe 2 is attached in any convenient and well known manner. is provided with any desired number of sleeves or thimbles 3, to which the sounding tubes 4 are connected, said sounding tubes being preferably located parallel with each other and also parallel with the exhaust pipe, but this is not absolutely necessary, owing to the fact that the exact arrangement of the tubes 4 with reference to each The head or sleeve 1 other is immaterial, except that they should be so arranged that they will be compact and be easily brought into and out of sounding condition.

The exit end of the exhaust head 1 is preferably beveled as best illustrated in Figs. 4 and 5. To the exhaust head or sleeve 1 is pivotally attached the cap or cover 5, the inner face of which is concaved and formed of such a size that it will close the exhaust head and at the same time rest upon the beveled end 6 of the exhaust head 1. The cap or cover (3v is pivotally connected by means of the ears or flanges 7 and the usual bolt or rivet 8. The cap. or cover 5 is also pro vided with the arm 9, which arm extends outward from the pivoted point of the cap or cover 5, and to the outer end of said arm is attached one end of the spring 10, the opposite end of said spring being attached to the lug bolt 11 or its equivalent. The spring 10 is for the purpose of normally holding the cap or cover 5 in opened position, such as shown in Fig. 4. The cap or cover 5 is also provided with the lever arm 12, to which lever arm is attached the operating cord 13, which operating cord may be of any desired construction and is extended and connected in such a manner that the cap or cover can be manually closed when it is desired to sound the horn.

The mechanism designed to actuate the cap or cover 5 does not pertain to the present invention, and is not illustrated as many ways may be devised, any of which may be employed.

For the purpose of producing or forming a slit or slot for the escape of air and gases when the cap or cover is closed the exhaust end of the thimble or head 1 is provided with the passages or channels 14, which channels or passages are arranged so that they will guide the air and gases across the inclined ends of the sleeves or thimbles 3, and when the cap or cover 5 is in its closed position the air and gases must escape through the channels or passages and by reason of the force of the exhaust blown or forced over the mouths or open ends of the thimbles 3 and the pipes or tubes 4. The purposes of forming the inner face of the cap or cover 5 concaved is to provide means for better and more equally distributing the air and gases in such a manner that the air and gases will be more directly forced through the passages or slits formed by the channels 1% and the rim of the cap or cover 5.

It will be understood that, the cap or cover 5 which comes in contact with the end of the thimble or head 1 should be provided with the beveled flange 0r rim 15, the face of which abuts and snugly fits the beveled end of said head, thereby cutting off the escape of air and gases between the channels 14:, by which arrangement the entire amount of the air and gases is utilized in producing sound.

For the purpose of producing what might be termed chime sound the tubes 1 are formed of difierent lengths, thereby varying the tone of the various pipes or tubes at. It will be understood that the ends of the tubes opposite their mouths should be closed, which arrangement is shown in Fig. 2.

Ihe inner edges of the passages 14: are provided with the lips or angled flanges 15, which are for the purpose of assisting in producing sound during the time the air and gases escape through the slits or passages when the cap 5 is closed.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is-

1. In an automobile horn, the combination of an exhaust pipe, a head connected to the extremity of said exhaust pipe, said head provided with a beveled outer end, a series of thimbles formed upon said head, said head provided with passages in its outer face leading to each of said thimbles, a piv- Gopies of this patent may be obtained for five cents each, by addressing the that portion of wind-chest, a

oted cap provided with a concaved inner face, said cap provided with a beveled flange adapted to fit the beveled end of the head and adapted to lie over the passages when closed, means for normally holding said cap in an open position and a series of tubes provided with inclined open ends connected to said thirnbles.

2. A. horn comprising an open body providing a wind-chest, horn-members associated with said body, means connected with the outer end of said body having rearwardly extending open channels, and a pivoted closable means adapted to fit over said channels to convert the same into windpassages leading from the outer end of said wind-chest to the mouth of said horn members.

3. A horn comprising a body providing a horn-member associated therewith, said wind-chest having at its outlet end means provided with an open channel directed rearwardly toward the mouth of said horn-member, and pivoted closable means capable of being closed over the out let end of said wind-chest so as to extend over said open channel to convert the same into a tubular wind-passage.

In testimony that I claim the above, I

I have hereunto subscribed my name in the presence of two witnesses.
